Error: Image is Missing Required Alt Property

What's Causing This Error

The error 'image is missing required alt property' usually crops up in the context of HTML and accessibility requirements for websites. In the HTML code, each <img> tag should contain an alt attribute to provide a textual description of the image. This serves several important functions:

1. Accessibility: Screen readers use the alt text to describe the image to users who are visually impaired.
2. SEO: Search engines use the alt text to understand the content of the image, which can help enhance your site's search engine optimization.
3. Fallback: If the image fails to load on a webpage, browsers will display the alt text in its place.

If the alt attribute is missing from an <img> tag, you'll encounter the 'image is missing required alt property' error. It means that one or more images on your website do not have proper alt text, which could negatively impact accessibility, SEO, and user experience.

Solution - Here's How To Fix It

To resolve the 'image is missing required alt property' error, you need to add appropriate alt attributes to all your <img> tags. Here's how:

1. Identify the Problem Images: Use tools like Google Lighthouse or W3C validator to identify the specific <img> tags without alt attributes.

2. Add Alt Text: Add an alt attribute inside each problematic <img> tag. The alt text should accurately describe the contents and purpose of the image. For example:

<img src="puppy.jpg" alt="A happy brown puppy playing in a field">

3. Review and Test: Once you've added alt text, review your changes to ensure the descriptions are accurate and representative. Don't forget to test your website for accessibility and SEO improvements as well.

Remember that alt text should be concise while clearly describing the image. Avoid stuffing keywords; instead, focus on providing value to users and search engines alike.
